[Q] Question about bootloader.

Hi. I have a Rogers Branded Sim-Locked Xperia Arc with Gingerbread 2.3.3, and my goal for this phone is to get Cyanogen Mod 7 Beta 11 on it.
I read that in order to flash the custom rom I need an unlocked bootloader. I also read in order to unlock my phones bootloader I need to be able to enter fastboot mode. Unfortunalty I cannot enter fastboot mode since I got my xperia arc directly from my Carrier Rogers. My question is if I purchase an unlock code from one of the various websites out there, and then unlock my phone would I be able to enter fastboot and eventually unlock my bootloader and then flash cyanogen mode 7? Thanks in advance

No.
As things stand, there's nothing you can do to get your handset into FastBoot mode - only factory-unlocked handsets are capable of doing so.

Thanks but im still kind of confused. What about this? http://forum.xda-developers.com/showthread.php?t=1037874
And so with any custom rom coming out i will need an unlocked bootloader?

That's a thread discussing the possibility of trying to enable Fastboot on handsets that don't currently support it.
But to the best of my knowledge, no significant progress has been made.

So, has any progress been made? Am I able to unlock my bootloader now and get cyanagen mod? Or do I still need a factory unlocked handset cause of the fastboot thing

Have a read of the general and development sections. ;-)

i read it but im still a little bit confused, to my knowledge the only way of unlocking my phone to put cynagen mod is to pay someone to remotely unlock my phone?

Unless you have access to SETool, yes.

[Q] R800a can not OTA update or enter fastboot, root problems? mode.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.
R800i, Android 2.3.3, Kernel 2.6.32.9-perf [email protected] #1, Build number 3.0.1.A.0.145

Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.

Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.

Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it

It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter

I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?

Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps

Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

Xperia ion Bootloader Unlocking & Relocking

Taken from [Tutorial] Xperia S/P/U/Sola Bootloader Unlocking & Relocking and modified slightly for the ion. I take no credit for this tutorial.
Quick tutorial for unlocking & relocking the bootloader of the Xperia ion.
This is the official way to unlock bootloader
Warning!
This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. SDCARD will NOT BE WIPED!!!
DRM keys WILL be lost forever
Why should I unlock the bootloader?
You can flash custom ROMs/Kernels.
You don't need to worry if the new firmware can be rooted or not as with unlocked bootloader you can always ROOT your device.
SE/Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011 line (they had ICS alpha/beta), so who knows may be SE/Sony may give early builds of ICS (JellyBean???)
Most of this is taken from lollylost100's his tutorial from ARC thread (all credits for that concise tutorial go to him, i have elaborated on a few things and added device specific changes)
[ Before we begin unlocking bootloader ]
Get the IMEI code for your device: type *#06# in phone dialer to find it out, note only the digits (no dashes)
Download the fastboot package with usb drivers (alternate drivers if the ones in package dont work)
Make sure u have a windows PC with USB cable to connect the phone
Power down your phone and keeping the Volume Up button pressed connect the USB cable to PC this will trigger FASTBOOT mode and windows will start driver installation, extract the above package and point the driver install to that location (usb_driver) folder
Once drivers are installed just disconnect cable and power on device
[ how to unlock ] (official way)
Go to: http://unlockbootloader.sonymobile.com/ and read everything!
At the bottom click 'Start Unlocking the Bootloader'
First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the phone dial pad and enter *#*#7378423#*#* to access the service menu.
In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Click to expand...
Click to collapse
After you have verified that you can unlock bootloader, scroll to the bottom of the page and click "Continue"
You will get "Are you sure prompt" accept it by clicking "yes i am sure" (i assume that you have read an understood it)
Then accept the "legal terms"
Finally you will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address
You should now receive your unique unlock key, its displayed on screen, SAVE THIS KEY SAFELY
Extract fastboot_with_Android_USB_file.rar and open fastboot folder
Hold SHIFT and right click on the background of the folder
Select 'Open command window here'
Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected
Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which you received earlier.
Your device should now be bootloader unlocked
If this tutorial is too much for you then itskapil wrote a step-by-step guide (and recorded a video also):
-Instructions: http://www.theandroidsoul.com/how-to...-play-neo-pro/
-Video: http://www.youtube.com/watch?v=LRH3pC7MhEA
(the above videos and some steps are for Xperia 2011 devices, but most the steps are same for Xperia ion)
Info on Relocking bootloader is in next post

Relocking bootloader
RELOCKING BOOTLOADER WILL ALLOW YOU TO GET NEWEST UPDATES & REPAIR DEVICE USING SEUS/PCC
Before we begin relocking the bootloader make sure that u have flashtool download & installed
You can get the latest version of FlashTool from:
http://androxyde.github.com/Flashtool/
Download link is under "Installation" tab
If you have not use FlashTool before read this thread:
http://forum.xda-developers.com/showthread.php?t=1526866
Download this FTF:
Xperia ion -> LT28-ION_Relock_bootloader_Dogsly-TEST.ftf // Mirror 1
Flash this FTF via FlashTool:
When it says enter flashmode, power down device and keeping VOLUME DOWN button pressed connect usb cable to phone, the device will now enter flashmode (green LED)
After this file is flashed reboot phone
Bootloader will now be relocked!!!
Incase device doesn't boot DO NOT PANIC... You can flash stock firmware FTF anytime to get back to stock ROM
P.S.: there is no official way to relock bootloader

So because my phone says I can't unlock the bootloader, does that mean I can never unlock the bootloader? Or do I have to wait to be able to root it first?
PS: I got my ion from Best Buy so is that why? Will I ever be able to unlock the BL ? I've rooted and unlocked my x10, back in the old days lol but I'm just wondering if there's any difference with getting a phone from at&t directly or from the sony store and best buy.

Have to wait to see if another way to unlock the bootloader is discovered. Root and unlocking the bootloader are two different things that accomplish or allow different things you can do on the phone.
IE rooting allows you to uninstall system apps & bloatware, backup apps/data, make changes to build.prop etc. Unlocking the bootloader will give you access to fastboot so you can flash custom roms/kernels and other images such as a pre-rooted system image to gain root.

I wonder. If we can not unlock the bootloader for some LT28at, why is there a key to unlock it? I did the Sony bootloader unlock for fun and apparently they have a key for my LT28at even though it says bootloader unlock is not allowed.

I understand that works for lt28i but I'm referring to lt28at the us model of the ion and why there is a bootlloader unlock code when we can't unlock it.

see if it works

Has anyone with an ion that has
Bootloader unlock allowed says Yes

tried to unlock it via the sony site and if you did and it was successful have you tried to relock it using the file linked above? Would be nice to know if that works.

Possible fix?
If the LT28i can be unlocked, what if we flash the international firmware on our LT28at's and then do the LT28i method? Maybe a stupid question but this is the first phone I've had that's a challenge to do stuff like unlocking and rooting. My last phone (HTC Aria) was extremely easy.

Kinda figured that

I tried to relock the bootloader. The flash pass but the phone can't turn on after that.
*I reflash the stock kernel again and the phone can power on now.
So here is the result, once you relock bootloader, you need to flash back the stock kernel in other to turn on the phone. Hopefully this will help those people who got stuck after relock bootloader.

Hello guys
I was just wondering, if bootloader unlock or flashing cutom kernel will allow to use sim cards from other mobile operators (European for ex.) ?
I have an ability to buy this device in us through my friend. but Im interested if I would be able to use it in Europe I was thinking of buying xperia p or s, but they dont have microsd card support.
Im not interested in using LTE networks. Just common 2g.
I planning to use it like a second android device as a multimedia player instead of my galaxy s wifi5.0. (because of good sound quality and other features).
Thanx a lot for responses

No. You can't unlock the bootloader of the lt28at and you can't sim unlock it either. Best bet is get an international version not one from the US.

I think you can switch the rom to international version but it will still be bootloader locked. Not sure about carrier

[Q] Unlocking and Rooting a R800AT

I've been through a few guides and tips, yet I am still having trouble unlocking the bootloader and rooting an AT&T Xperia Play. I've tried using flashtools, downgrading firmwares, sonys official unlocking tool couldn't work, the manufacture date is past some programs limitations, and one last one suggested using gingerbreak and .184 UK firmware, however the .184 UK firmware is missing from links.
If anyone could help me out, or push me in the right direction, it would be greatly appriciated because I am completely lost.

I suppose to throw in some tests I did, after checking the rooting status using *#*#7378423#*#* on the dialer, nothing shows up indicating any rooting status, so the bootloader is still locked I suppose. The IMEI is 357593041206718, which is 15 characters and cannot be used for sony's official unlocking. The manufacture date is 12W15, past some companies ways to patch the boot loader, namely fastgsm's. I tried messaging the program from testpoint I guess (cannot post links but the second option to unlock in the wiki) to try and use their pay service.

A bit of progress, I believe I have unlocked and rooted the phone. When turned off, plugged in, and holding search, a blue light now appears. I ran super one click and got it to allow super user! Also, I got here by using an outside service to unlock my phone by shorting the two pins on the phone and plugging it in as well as using a credit.
So anyways, now even though WiFi is on and working, I cannot connect to the play store. Also confused at how to install a custom recovery software and how I can get my phone to ICS.

If your looking to install a custom recovery software download x-parts from the android store and it does recover root access however you can not install custom roms due to your locked bootloader. Yes you can install root or su on a locked bootloader. But to install a custom rom if that is what your going to do you need a unlock bootloader. In this case using a program called settool. Unlocking your bootloader is not free and I recommend alejandrissmo a reputable XDA member and he a site you can unlock your bootloader there.

Thank you for the reply, I have been able to unlock the bootloader through a difference source, same concept and did cost a tiny bit. Anyways now I'm lost trying to find a ROM that works, tried the AOKP customized release but wifi and bluetooth were not working. Have any suggestions?

Did you flash the wifi modules that went with the kernel you used? You could try to re-flash them if you did.

[Q] Bootloader unlock allowed: NO

Hello, guys
So i got a series of problems since i unlock the simlock,
I just got my new zl a few days ago, the device was lock to Bell.
I rooted the device and after that, i got a code and enter it to the sim free status.
but here is the problems:
when i check the rooting status, it says bootloader unlock allowed: no. It will fail on if unlock straightway.
As i know, it should turns to yes, but it didn't, hwo come? Also, i flash the recovery, but it only works on first time when i get in the recovery mode.
I selected "reboot system now", and cwm point out that will flash stock recovery, no matter i selected yes or no, recovery doesn't work on next boot.
I used to have Xperia S, it was also says no, after i unlock it turns yes. It wasn't happens on my ZL! I tried to flash a new ftf and wiped all the data,
it still says no. Anyone has a same situation? Can anyone fix it?

So do I, maybe Bell not allow BL to be unlock? Recovery can't even work correctly without BL unlock.
Before ZL. My XS was locked to Rogers. As I said, my XS shows BL unlock allowed after typed in the unlock code. Which mean Bell locked the
BL deadly?
I will keep following this god damn sh!*
nutzuTo, thx anyway.

Can anyone confirm that the Bell Mobility (Canada) ZL's are permanently bootloader locked? I want to get one off the used market, but won't unless it can be fully unlocked.
Thanks

Maybe I didnt read the post properly but unlocking your SIM doesnt unlock the bootloader as well. It simply allows your phone to be used with different carriers. I have the C6506 from Rogers, flashed the stock Sony ROM, rooted the phone and installed TWRP and CWM. My bootloader remains locked. I dont have the need to flash the Kernel so no point in unlocking the BL. Besides, unlocking your BL voids the warranty.
Anyway, I have played with the C6506 from Bell in a store and the BL is set to "Bootloader unlock allowed: No" so its pretty safe to assume that all Bell and Rogers phones cannot be unlocked. This doesnt stop you from rooting, flashing or installing recovery.

Simlock and bl lock two different things
if your bl unlock says yes that means you most have one direct from factory
if your bl unlock says no you either have it on a plan or bought it full price through bell or rogers
carrier branded usually bootlocked

Thanks for the replies guys.
I know that custom rom / root / recovery can be flashed, but coming from a galaxy nexus and n7, I'm used to being able to try out different kernels.
Can custom kernels be installed if they're part of the custom ROM? Usually the rom cook puts in the kernel of her/his choice but we can freely change after.
Anyone feel the need to change kernels or the standard one is good enough?

"Can custom kernels be installed if they're part of the custom ROM? Usually the rom cook puts in the kernel of her/his choice but we can freely change after."
Yes.When you are thinking about installing/flashing custom rom but want different kernel DL and extract the boot.img(name may vary but must end .img)
Now FLASHTOOL is sonys verision of the "Nexus Toolkit" . If you dont have adb setup download and install program to C: as well as all drivers needed. Now in the flashtool folder copy and paste the ".img" kernel into the folder named x10lib.
After double click folder labeled "x10lib" once inside the folder open command prompt window by holding left shift and right click anywhere in the opened x10lib folder.
now make sure your device is connected to your pc in fastboot mode (hold vol +) led will emit blue light.
enter command
"fastboot flash boot boot.img"
followed by
"fastboot reboot"

yes i first used doomlords kernel (Xperia ZL) mainly for the fact that it came with cwm recovery .thus making the need to flash cwm seperatley an extra non needed step. this was before i flashed 4.2 update.

With that said, how would I go about flashing CM or something else aosp based with a locked BL xperia zl?
Can flashtool unlock my BL to allow this?
I ask because I clean see an option there, just haven't wanted to muck about with things I don't yet understand lol

sadly only way to change bootloader unlock allowed to yes is to carrier unlock from ur carrier directly. anyone else and it will not change bootloaded unlock allowed no to YES. I have called bell and sony. sony told me i have to carrier unlock through bell to get it to change to yes only thing is. you have to have had your phone for 90 days and it costs75$ added to ur bill.
